Abstract (en)
The arrangement includes first (3) and second (4) patterns such as photolithographic patterns of electrically conductive indicia provided on respective first (1a) and second (2a) surfaces of the components (1, 2) to be positioned. The patterns (3, 4) are adapted for relative movement in sliding contact relationship along the positioning axis (x). The patterns of electrically conductive indicia (3, 4) define electrically conductive pads at least one of which reaches the condition of being either open or closed when the surfaces (1a, 2a) on which the patterns (3, 4) are provided reach a given position along the positioning axis (x). Sensing is preferably effected by means of an amperometer. <IMAGE>
